The Joliet Township Animal Control Center provides trap rentals at $50 for five days. They'll pick up any animals that are caught.

"It's a very simple trap, and they can set it themselves," Animal Control Director Sarah Gimbel said.

Leon Bilbrew, a licensed skunk trapper with Ace In a Hole Wild Animal Control in Joliet, said he hasn't had a busier year in eight years. There should be double the trappings this year, at least 120, he said.

According to the Illinois Department of Natural Resources, the state's skunk population has doubled over the past few years. Increases have often been in the double digits over the last decade, the department said.
